13.The technical measures and structure,applied principles of blastproof of ventilation shaft at excavating face,specific operational method and prospective effect are described.
14.Heterogenous expression of active nitrile hydratase (NHase) was focused for its great potential in genetically evolution of the operational stability of NHase.
15.This paper introduces the operational principle, system architecture and major functionalities of a comprter-centered LD-system, which orients the thunderstroke using time difference.
16.Based on the submarine missile launcher's operational requirements and improving the level of standardize,communalize,serialize and modularize,discussed the problem of common frame launcher.
17.The designers of these circuits based them on the same concept: a fully integrated, single-die-IC switching regulator and a micropower operational amplifier.
18.Ambipolar transistors are attractive for realizing complementary-like organic integrated circuits, which operate with low power dissipation, wide noise margins and great operational stability.
